Electromyographic Analysis of Embouchure Muscle Function in Trumpet Playing

摘要: A review of the pedagogical brasswind literature revealed that varying and contradictory opinions concerning embouchure function are based primarily on theory or conjecture. The physical physiological functions involved have received very limited attention from researchers. This experimental study investigated possible effects register, intensity, subjects' proficiency level electromyographic potentials (a measurement muscle activity) four facial muscles 18 trumpeters. Electromyograms were made simultaneously upper lower lips levator depressor mouth corner using Basmajian's indwelling, fine-wire electrodes during 51 trumpet performance tasks. Statistical analyses data several interesting differences between advanced beginning trumpeters activity preceding following tone, lips, in-the-lips out-cf-thelips playing musical technical passages.
